Iraq also operated French radars

Thomson TRS 2215 / 2230 3D Early warning radars.

Manufactured by: Thomson-CSF Airsys Bagneux.
This family of E/F-Band air defence 3-D radars, employing electronic phase scanning in elevation, is derived from the height-finding radar SATRAPE which has equipped the French Air Force.
The primary radar antenna is a direct radiation array of stacked linear subarrays fed by two vertical distributors used to form the sum and the elevation difference channels. Each linear subarray contains elementary sources radiating a circularly polarised wave. The two waveguides allow monopulse operation to perform the height-finding function. Digital electronic phase shift networks inserted between the elementary feeds and the corresponding directive couplers control the pointing of the beams.
The transmitter is an amplifying chain transmitter using a crossed field amplifier as its final tube. It permits the use of the pulse compression technique and that of pulse-to-pulse frequency agility.

The receiver circuits comprise the anti-jamming chains and three angle error chains. The MTI device processes the signals received from any one of the three lower beams by programming. The extractor performs the extraction of primary and secondary plots and allows them to be associated together. It is followed by a plot processing system which computes altitude and filters plots so as to transmit only useful data. The device generates the data in a digital form permitting the transmission of tracks to a remote centre. The monitoring desk groups the monitor controls of the station's operation.
TRS 2215s are quoted as being supplied into France's Strida (Système de traitement et de représentation des informations de défense aérienne) national air defence network.





The tactical 3D- Air-defense radar Thomson Master-T developed by the Thomson CSF Air Command and Control Systems Company is as a classical surveillance radar a member of an S-Band radar family including the fixed site variant (Thomson Master-M) and a smaller Multifunction radar (Thomson Master-A).
The phased array antenna rotates with 6 r.p.m. and scans the airspace with pecil-beams up to an altitude to 100 kft. The phased array is composed of 35 linear arrays with 35 phase shifters. During the receiving time the radar uses the monopulse procedure.
The solid state transmitter uses the pulse compression improving the range resolution. The radar data processing is fitted with a dedicated channel to track ballistical missiles beyond the normal cosecant squared antennae pattern up to a slant range of 350 kilometers and an elevation angle up to 70 degrees.
